The terrestrial adults have stout bodies and legs, widely spaced eyes, and well-devel.........Adults are most common in bottomland forests in or adjoining floodplains, but occur sporadically in upland forests and in mountainous regions where suitable breeding sites are available. Felix et al. ...The adults migrate to breeding ponds during the late winter and early spring and can be found crossing roads on rainy nights or gathering around the margins of ponds. Groups of courting adults can be ...At sites where forest buffers that surround the breeding ponds are intact, local populations are thought to be limited by density-dependent interactions that occur during the larval stage. Crowding g......S5G5

Pseudacris nigrita
Southern Chorus Frog		Pseudacris nigrita hybridizes with P. fouquettei across the Pearl River between Louisiana and Mississippi. The hybrid zone was estimated in 1976 to be from 8.7–14 km wide, but a recent a......The advertisement call is a slow metallic ascending trill with 5-10 notes that are readily distinguishable within each trill. Calling rates are temperature dependent, but trills are typically issued e...The juveniles and adults are primarily found in sandy or loamy upland Coastal Plain habitats. Pinelands and mixed pine-hardwoods are commonly used. Representative habitats include pine flatwoods, xer...The adults are most readily observed during the breeding season when they are calling from breeding sites. They are occasionally seen crossing roads on rainy nights. ...Local populations are organized around local breeding sites and each typically consists of no more than perhaps a few hundred to a thousand or so adults. Semlitsch et al. (1996) monitored populations ...Populations in North Carolina appear to have declined during the last few decades and this species is currently listed as S2 within the state. Most of our records are > 20 years old, and there are ver...S2G5SC
Pseudacris collinsorum
Collinses' Mountain Chorus Frog		Until recently, the Mountain Chorus Frog (Pseudacris brachyphona) was treated as a single species that ranged from mountainous regions of eastern Kentucky, southeastern Ohio, and western West V......The advertisement call is a series of short, nasally 'wreaks' that are repeated over and over and issued about every second or so depending on the prevailing temperature. The call is distinctive and ...Local populations are often found near the interfaces of forested and more open habitats such as agricultural fields or roadways. Although breeding often occurs on deforested land that is rather dista...Local populations are most readily detected by riding roads on warm, rainy nights to search for migrating adults, or by listening for calling males during the breeding season. The small egg masses can......Populations in North Carolina show no evidence of widespread population declines and appear to be stable. ...S2G2SC
Necturus lewisi
Neuse River Waterdog		Necturus lewisi was originally described by Brimley (1924) as a subspecies of N. maculosus, but has been recognized since 1937 as a valid species. Electrophoretic and chromosomal compari.........Braswell and Ashton (1985) found that populations in the Piedmont Plateau and along the Fall Line were most likely to be encountered in clean, moderate to swift flowing streams with widths over 15.5 m.........Resurveys of N. lewisi since Braswell and Ashton's (1985) comprehensive study show that this species has experienced significant and widespread declines throughout its range. The most notably a...S2G2TT
Hyla andersonii
Pine Barrens Treefrog		Duellman et al. (2016) elected to split treefrogs in the genus Hyla into two genera. Hyla (sensu stricto) refers to a group of species that are found in Eurasia, while a new genus Dr......The advertisement call of the Pine Barrens Treefrog is very similar to that of the Green Treefrog. The call has been described in various ways (Dodd 2013, Noble and Noble 1923), but is perhaps best re...Hyla andersonii has rather specialized habitat requirements. It is generally associated with pocosins, acid bogs, shrub bogs, and seepage areas that are surrounded by sandy habitats and have cl...Adults are most easily observed during the breeding season when the males are calling. ...Local populations are often small (e.g., Sorrow 1982), which reflects the small size of many seepages and bog ponds that are used as breeding sites. Moler (1981) noted that fewer than a dozen males ca...H. andersonii is an IUCN Red List near-threatened species and is considered to be at risk of decline because of habitat loss (IUCN 2016). It is also listed as imperiled in Florida, threatened i...S2G4T
Cryptobranchus alleganiensis
Hellbender		The Hellbender (Cryptobranchus alleganiensis) is an unmistakable giant salamander that inhabits cool, rocky streams in the eastern US. Taxonomists have traditionally recognized two subspecies t.........Hellbenders inhabit large, rocky, fast-flowing streams that are well oxygenated. They are generally found at elevations below 762 m (2500’) and are most commonly found beneath large rocks or rocky she......Factors that regulate local populations are poorly understood, but competition for large rocks that are used for cover and brooding may set an upper limit on population size.
